ABSTRACT:
A water filter assembly mounted to an inner surface of a refrigerator and accessible from within a refrigeration compartment of the refrigerator. The filter assembly includes a first housing part, a second housing part, and a replaceable filter cartridge. The first and second housing parts cooperate to define a fluid-tight chamber for receipt of the filter cartridge. The first housing part includes an inlet port through which unfiltered water may be introduced into the chamber and an outlet port through which filtered water may exit the chamber. The second housing part surrounds a portion of the first housing part and provides a volume sufficient to hold the filter cartridge and any water within the chamber when the second housing part is released from the first housing part to replace the filter cartridge, and thereby prevents or minimizes spillage of water from the filter assembly during filter cartridge replacement. A shield member is disposed within the refrigeration compartment and cooperates with a cabinet wall to define a filter compartment which surrounds the filter assembly. A heater disposed within the filter compartment adjacent the filter assembly and is operable to heat the filter assembly to prevent freezing of water contained therein.
